From a systematic analysis of the energy-dependence of four antibaryon-to-baryon ratios relative to the antikaon-to-kaon ratio, we propose an alternative approach determining the strange-quark chemical potential ([Formula: see text]). It is found that [Formula: see text] generically genuinely equals one-fifth the baryon chemical potential ([Formula: see text]). An additional quantity depending on [Formula: see text] and the freezeout temperature ([Formula: see text]) should be added in order to assure averaged strangeness conversation. This quantity gives a genuine estimation for the possible strangeness enhancement with the increase in the collision energy. At the chemical freezeout conditioned to constant entropy density normalized to temperature cubed, various particle ratios calculated at [Formula: see text] and [Formula: see text] and the resultant [Formula: see text] excellently agree with the statistical-thermal calculations.
